ELECTRIC-LIGHT rrxruan.

Application filed April 14, 1921; serial No. 461,312.

To all whom it may concern:

Be it known that I, Fos'rnn GUNNISON, a citizen of the United States, residing at 1051 Ocean Avenue, in the borough of Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Electric- Light Fixtures, of which the following is a specification.

This invention relates to an improvement in electric light fixtures, and more particu-' larly to the construction and arrangement of the parts, as will be more fully hereinafter pointed out.

Electric light fixtures of the ceiling type, as herein described, have heretofore been cumbersome as to packing for shipment and .inadaptable t0 the variation in the size of the bulb used in the fixture. My invention solves both of these problems by furnishing a device which can be readil taken apart, and the rincipal parts of w ich can be nested togetlier for shipment. It is also constructed and arranged so that the louvers and glass bowl can be quickly and easily adjusted as to their distance from the husk, so that a larger or smaller bulb can be used in the fixture as desired. Also my invention eliminates rivets and riveting, which is especially important with enameled parts, such as the louvers of this device.

Referring to the drawings Figure 1 is a perspective of the complete device, showing a portion of the husk broken away; Figure 2 1s a perspective of the main portion of the husk having two series of slots; Figure 3 is a top plan view of the husk cover; Figure 4 is a perspective of a strap with a suspension hook therein, and showing the upper and lower louvers in dotted outline; Figure 5 is a top plan view on the line 5-5 in Figure 1; Figure 6 is a section of the upper louver showing one set of slots; Figure 7 is a perspective of the louvers and bowl nested for shipment, one end being broken away in order to show the position of the parts.

In the drawings 8 is a canopy secured in the usual way to the ceiling, and through which a cord 9 containing the wires passes,

and to the cord 9 is secured at its lower end a socket 10 0f usual construction. To

the to of the socket 10 is secured a husk or soc et cover 11 by means of screws 12, which may be adjusted through theslots 13 of the cover 11 de ending upon the variation in the size 0 the socket '10. The cover 11 also has a hole 14 through which the cord 9 is adapted to pass. having a flange 16 is adapted to pass over and rest by said flange 16 on the cover 11. The husk 15 has slots 17 from which hooks 18 are adapted to be suspended. In Fig. 2 is shown an upper and lower series of slots 17. v

The lower ends of hooks 18 support metal straps 19, which rigidly secure together an upper conical louver 20, a lower conical louver 21, and a glass bowl 22.

The straps 19 have upturned lips 23 which are adapted to pass through slots 24: of the upper louver 20, and straps 19' are also looped at 25, so as to project through slots 26 in the upper louver 20, and the lower ends of the hooks 18 are curved at 27 so as to pass through loops 25 and are again bent and curved at 28 so as to rest in the. same plane and rest upon the upper side of louver 20. The straps 19 are again looped at 29 so as to project through slots 30 of the lower louver 21, and through which loops 29 cotter pins 31 are adapted to pass so as to secure the straps 19 in fixed position to the lower louver 21. The straps 19 also are bent at 32 so as to fit over the outer edge of the lower louver 21, and are finally again bent at 33 so as to form'curve spring members 34': adapted to fit over the outer edges of the glass bowl 22.

My device when shipped in the knockeddown or nested condition, as shown in Fig ure 7, can be readily put together in the following manner:

Having first secured in position, as already described, the husk 17 i and socket cover 11, the looped end 23 of the strap 19 is first inserted through the slot 24 from underneath, and the loop 25 is then pressed up through the slot 26, and the turned and curved end 28 of hook 18 is slipped through said loop ,25 so that 28 rests upon the up.- per surface of the upper louver '20. The looped portion 29 of the strap 19 is then pressed through the slot 30 on the upper side of the lower louver 21, so that it projects through the same, and a cotter pin 31 is slip ed through said loop- 29 on the underneat side of lower louver 21 and spread in the usual way to retain it in position. In my device t ree such straps are A husk 15 shown, and after all three have been mounted as described, the louvers can then be suspended from the husk 15, in whichever group of slots 17 -may be desired by means of the hooks 18. The glass bowl 252:

strap mem er having loop portions insertible through each of the slots, and a detachtill able locking means for maintaining the strap in engagement with the louvers, said strap member terminating in an inwardly bent portion for supporting a glass bowl.

2. In a lighting fixture, the combination of a series of spaced louvers each having a slot through the body portion thereot, a supporting strap having portions detachably engageable in said slots and other portions engageable with the louvers away from the slot to hold the same in spaced relation, said strap terminally provided with means for supporting a glass bowl.

3. In a lighting fixture, the combination of a series of spaced louvers each having a slot through the body portion thereof, a strap member provided with a series of intediate looped portions, each of said neeaeie looped portions detachably engageable with the louvers through the slots in the latter,

said strap member terminally provided with means for supporting a glass bowl.

4. In a lighting fixture composed of a series of louvers each having a slot therethrough, and a member for supporting the louvers in spaced relation consisting of a continuous metal strip having parallel portions for engaging the surface of the louvers and a portion for spacing the louvers and ofiset portions detachably engaging a louver through the slot therein.

5. In a lighting fixture'composed of a s ries of spaced louvers each having a slot through the body portion thereof, a continuous metal strip having a series of offset portions intermediate its ends engageable within the slots in the louvers and a cotter pin for detachably locking the oilset portions within the slots.

6. In a house lighting fixture composed of a series of spaced louvers each having a slot through the body portion thereof, a member provided with a series of intermediate looped portions passing through said slots and means on the looped portions for detachably securing said members to the louvers.

ln testimony whereof I afiix my signature.
